We will proceed our organized method to detecting a swimming pool heating system by looking at what to do when the light in the command pad on the leading of your Sta-Rite swimming pool as well as medspa heater that is labeled “service heating unit” is lit. (We will http://www.techne.com wage the presumption that you recognize every little thing from section one.) This time around you will have to take out the sides from the heating system just before disconnecting power to the heater so that you can review the codes on the board attached to the topside. After getting rid of the sides, you will see the large topside that is still connected to the heater. Listed below the topside is a metal panel that keeps the topside in position. Under this panel there are two locking pins (cotter pins). Very carefully get rid of both pins as well as save them someplace protected till reassembly. Carefully remove the top and also turn it inverted. You will certainly view a light lit on the board you are taking a look at when you transform the topside over. The light will certainly be alongside a code that is written on the board.

The initial code that you'll view on the left side of the board will be PS. This is the code for the stress button. We covered the stress button in section one. If this light is lit go back to sector one and examine that segment. If necessary follow the instructions to replace the stress switch.

The following code you'll see on the board is HLS. If you have a controller on the technology you will certainly need to bypass it currently. You will should very carefully separate the power from the heater. After you are sure that the power is separated, you will certainly should locate as well as open up the high-voltage closet. This cabinet is a metal box in the middle of the heating unit. If you are taking a look at the cabinet, there is usually a screw on the top right side. Loosen the screw and also the door will certainly swing down toward you. You have to be remarkably careful when working in this box and only doing this when you are sure that the power to the heating unit is OFF.

You will certainly need to bypass the firewall program security user interface. To do this you will need a short cable with stab-tab ports. If you have a controller and it was effectively set up the cable may have been left in the box by the tech that installed the controller. Otherwise you will have to make this jumper wire. At this point search in your owner's handbook to locate both appropriate pins to attach to. If you have a controller or are utilizing a firefighter's button this is where your command should be hooked up. If you have a controller and it is not linked below, it could be the source of your troubles as well as either have a certified tech deal with the issue or remedy it yourself.

You must take care not to place the jumper cord on the power terminals or you will ruin your heater by burning up the digital device. Usage your handbook to find where the fire fighter's button is expected to be affixed and also carefully attach your jumper between these terminals. If you now turn on the power and also the heating system functions without any problems, your problem depends on the controller or the circuitry going to the controller. You will need to trouble shoot this device.

If you still have the very same trouble with your heating system. (“service heater” light comes on), leave the jumper in position as well as verify that the pump is on and that you have excellent water circulation. Make certain once more with your meter that the pressure switch is not cycling. It ought to review as a dead short. (View segment one) With great water flow verified as well as the “solution heater” light on, your issue could be among the thermo-regulators in the safety system.

Considering that we started this with the indication light on the board lit alongside HLS, the first point we are visiting examine are the cables going to the high limitation button. The high limitation switch is located near all-time low on the left side of the water manifold as you admit. To view it you should get rid of the side cover on the water manifold. The screw that holds the cover is on the leading of it. You have to see to it that the orange cables going to the switch are in one piece, attached and also not corroded. If the wiring excels, use your multi-meter to examine that the high limitation switch reviews as a dead brief. If it checks out open and the water is not over 104 F, replace the higher limit switch. If this does not fix your trouble you might have a bad control panel as well as it will certainly have to be switched out. Testing the control board is a quite involved procedure as well as will be managed in a later sector.

This is the end of segment two as well as has taken you with part of the safety circuit in the heating system and 2 of the sign lights on the board. We will certainly continue on with our systematic diagnose of issues on the Sta-Rite swimming pool and health spa heating system in the following section.
